Agenda > Java EE 5 versus Java EE 6> GlassFish v3> NetBeans GlassFish Support> Eclipse GlassFish Support

Overall Goal For Java EE 6

> Make the platform:● Easier to use● More flexible, adaptable● Easier to learn● Easier to evolve going forward

Profiles

Major new Features in Java EE 6> Profiles

● targeted bundles of technologies> Pruning

● Make some technologies optional● CMP, JAX-RPC...

> Extensibility● Embrace open source libraries and

frameworks● Zero-configuration, drag-and-drop for web

frameworks, web.xml fragments> Ease of development

Ease Of Development> Ongoing concern> This time focus is the web tier> Lots of opportunities in other areas, e.g. EJB> General principles:

● Annotation-based programming model● Traditional API for advanced users● Reduce or eliminate need for deployment

descriptors● Get technologies to work together well

Servlet 3.0 Highlights> Annotation-based programming model

● @WebServlet @ServletFilter etc.> Modular web.xml descriptor:

● WEB-INF/lib/mylibrary.jar → META-INF/web-fragment.xml

> Annotations and web fragments are merged> Programmatic API for dynamic registration of

servlets> Async APIs

● Useful for Comet, chat rooms, long waits

EJB 3.1 Highlights> Singleton beans: @Singleton> No interface view: one source file per bean> Calendar timers:

@Schedule(dayOfWeek=“Mon,Wed”)● Non-persistent timers (tied to a JVM)

> Async business methods: @Asynchronous● Methods must return void or a Future<T>

> Global JNDI names for beans● java:global/(app)/(module)/(bean)#(interface)

Session Bean with Local Business Interface...OLD...

<<interface>com.acme.HelloString sayHello()

com.acme.HelloBean

public String sayHello() { ... }

@EJB private Hello h;...h.sayHello();

HelloBean Client

10

Optional Local Business Interfaces

> Sometimes local business interface isn't needed> Better to completely remove interface from

developer's view than to generate it> Result : “no-interface” view

● Just a bean class● public bean class methods exposed to client● Same behavior and client programming model as

Local view● Client acquires an EJB component reference instead of

calling new()

11

Session Bean with “No-interface” View

@Statelesspublic class HelloBean { public String sayHello(String msg) { return “Hello “ + msg; }}

12

No-interface View Client

@EJB HelloBean h;...h.sayHello(“bob”);

Web/EJB Application in JavaTM EE Platform 6

15

EJB “Lite”

> Small subset of EJB 3.1 API for use in Web Profile

> Broaden the availability of EJB technology● Without losing portability

> Same exact Lite application can be deployed to Web Profile and Full Profile

● Thanks to simplified .war packaging

16

“Lite” vs. Full Functionality

Lite > Local Session Beans> Annotations / ejb-

jar.xml> CMT / BMT> Declarative Security> Interceptors

> (Also requires JPA 2.0 API / JTA 1.1 API )

Full = Lite + the following:

> Message Driven Beans

> EJB Web Service Endpoints

> RMI-IIOP Interoperability

> 2.x / 3.x Remote view> 2.x Local view> Timer Service> CMP / BMP

17

EJB Component Testing

> It's too hard to test EJB components, especially the Local view

● Forced to go through Remote facade or Web tier● Separate JVM™ instances needed for server and

client> Support for running in Java SE exists, but...

● Not present in all implementations● No standard API for bootstrapping, component

discovery, shutdown etc.

18

New Features

> Singletons> Application startup / shutdown callbacks> Calendar-based timer expressions> Automatic timer creation> Simple Asynchrony

19

Singletons

> New session bean component type● One singleton bean instance per application per

JVM● Provides easy sharing of state within application● Designed for instance-level concurrent access

> Lots in common with stateless / stateful beans● Client views (No-interface , Local, Remote, Web

Service) ● CMT / BMT● Container services: timer service, injection, etc.● Method authorization

20

Startup / Shutdown Callbacks

@Singleton@Startuppublic class StartupBean { @PostConstruct private void onStartup() { ... } @PreDestroy private void onShutdown() { ... }

21

Timer Service Features

> Calendar-based timeout expressions > Automatic timer creation> Non-persistent timers> “Cron”-like semantics with improved syntax> Named attributes

● second, minute, hour ( default = “0” )● dayOfMonth, month, dayOfWeek, year (default = “*”)

22

Calendar Based Timeouts // The last Thursday in November at 2 p.m.(hour=”14”, dayOfMonth=”Last Thu”, month=”Nov”)// Every weekday morning at 3:15 a.m.(minute=”15”, hour=”3”, dayOfWeek=”Mon-Fri”)// Every five minutes (minute=”*/5”, hour=”*”) For ex:// Callback the 1st of each month at 8 a.m.

@Schedule(hour=”8”, dayOfMonth=”1”) void sendMonthlyBankStatements() {...}

Java EE 6: Summary

> Smaller, more agile platform: profiles, pruning, extensibility

> Ease of development still a major focus area> Component specs ready for public review> Open source implementation in GlassFish v3
